I eat fatty red meat, coconut oil and fish oil daily, and a bit of green veggie a few times a week. Been so since January. No sugar, no starch, no fruit. My body has been really happy with it. Hormonal hunger signals are much more regulated, I can actually go all day without a meal and feel fine (and exercise), and my sleep has improved.
After fully keto-adapted, I tried to incorporate some starch post work out (sweet potato), and my body reacted badly; I felt starved and irritable again between meals, and woke up at 3am staring (like I used to on carbs all the time). So, I gave that up fast.
My workouts are heavy weight lifting (sets of five), and rock climbing. Doing that on ketosis has been brilliant. I never run out of energy; its slow and steady like diesel fuel. BUT*** hiking up mountains for hours now I am 25-35% slower, and my legs burn A LOT more; I used to be the fastest guy doing that when I guzzled carbs on the way up.
Even before my current ketosis diet, I didnt tolerate carbs very well UNLESS I was in the midst of some hard, long cardio workout like climbing up a big mountain for hours or cycling hard. Then, my body seemed to utilize and metabolize them great, as long as I took the majority of them DURING and POST hard cardio workout, NEVER before. On my off days, my body went back to not tolerating much carb. My heartrate has to be high for duration and my muscles hot for my body to use carbs for energy properly it seems; im normally insulin resistant unless im exercising cardio hard.
For weight training, and rock climbing, ie strength training, ketosis works great. I actually feel STRONGER. But for any time my heartrate goes up and stays up, like hiking a mountain, I feel fatigued and slow.
Back to the present. Being in ketosis for so long, my body has become even more insulin resistant in the muscles due to glucose sparing for the brain, as Ive read on here several times is the usual way the body adapts to ketosis conditions. So now, im REALLY insulin resistant, and carbs REALLY bother me.
I need to be able to eat carbs when Im climbing up a big mountain, which is about once per month. But I dont want to eat them at all unless im doing that; now that I am in ketosis carbs bother me more than ever.
Is there any way to live in ketosis most of the time, ie stay adapted, and use carbs for fuel occasionally when conditions warrant, i hiking a big mountain, without "practicing" carb intake in the off times?
Has anyone done this? Can I have my cake and eat it too?
